BP's need floor space. Not height. I would suggest investing in a cage made for snakes rather than an aquarium for fish. You snake would be likely to use the floor space much more than the height.
Bp's are also clumbsy climbers, and will hurt themselves if allowed to go to such heights.
Having a tall tank is also a lot harder to keep proper humidity and heat over a short but deep cage.
Check out reptilebasics.com, there are some very nice cages that will appeal to the eye and also meet all the needs for your snake.
edit: 82 is too cool for bp's. You really want to offer a hot spot of 90-92, and the ambients be in the 80's. Humidity needs to be around 55-60%.
